Each year the boat is worth 100-12 = 88% ( or 0.88) of the year before
after 12 years the boat is worth 12050 * 0.88^9 = $3813.56
He is wrong...
2 1/2 + 3 3/5 = 97/20
Simplified, I believe the answer is 4 17/20
7/8 = x/48
Perform cross multiplication:
a/b = c/d
ad = bc
a = 7 ; b = 8 ; c = x ; d = 48
7*48 = 8x
336 = 8x
336/8 = x
42 = x
7/8 = 42/48
42 ÷ 6 = 7
48 ÷ 6 = 8
Answer:
It's b
it's kinda hard to explain but it ends up showing .7x.5 on the example, so your answer is B
